Merry Christmas from Leiden!

#MerryChrismas #Xmas #Christmas #Sleutelstad #Leiden #Bloomscrolling

A branch covered in pink blossoms against a blue sky.

The City Hall and Koornbrug in the city center of Leiden. The bridge over the canal has a grey roof, and a triangular tympanum and columns in pale yellow. The Sun hits it and the City Hall building behind it. The city hall building is of red brick, and the tower is topped with green copper decorations and a golden wind vane. In the foreground we see a parked cargo bike with the cargo part covered in canvas as a little tent for kids. The trees are bare and the sky is blue. Nobody to see.

The old Astronomical Observatory of Leiden. Part of the building is off-white, but the front part is red brick. We see four grey cupolas on the back part of the building, and a normal grey roof on the front part. The Observatory is situated inside a botanic garden along a canal. The sky is pale blue and the trees are bare. The sun hits the entire scene.

Picture of the inside of the Citadel on top of a small hill in the Leiden city center. Picture is taken from the top of the wall, looking at the walls on the other side, with the city hall building in the background. The trees inside the walls are bare and the sun is hitting them and a part of the wall. The sky is a pale blue.
